joint on the foot lanch, so that thedavit can be lowered down alongsideand within the bulwarks entirely out of the way, the davit remaining inand attachedto the socketready to replace for use; and I hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawing, making part of this specification, wherein- Figure l,shows a section of the bulwarks, with the davit in place, ready for use;Fig. 2, shows the davit, laid down against the bulwarks, or stowed awayFig. 3, is a plan, on larger size, of the lianch and socket to receivethe end of the davit; Fig. 4:, is a longitudinal section, and Fig. 5, isa cross section, throughthe center of the socket.

The like marks of reference denote the same parts, in all the gures.

a, is a foot plate, formed to set on the deck, or as shown, of the forniof the plank shear, with the water ways and deck; this plate a, issecured by bolts 1, to the part of the vessel to which the davit isattached, and is formed with a `square block c, having in the top asocket, that receives the projection, or half globe 2, of a socket c?,that is formed as a short cylinder to receive the lower end of thedavit,7 and around the square base of the socket ci, on the top face ofthe socket c, are lanches 4f, formed as shown, to support the socket CZ,in addition to the projection 2, in the socket c.

On one side of, and formed with the socket d, is a joint 5, that entersbetween two lugs or ears, 6, on the ilanch a, against the side of thesocket c, through which is a e pin 7, forming a joint: I prefer this pin7,

to be of brass,`to prevent rusting: This joint allows the socket d, tobe turned up, into the position shown in Fig. 2.

e, is the lower end of the davit, formed round to enter the socket al,in which it is secured but allowed to turn, by a pin 3, through the sideof the socket, entering a semi-circular groove around the part Ve, of

the davit this part e, when t-he davit is l in use, stands vertically,or nearly so, and is supported by a forelock 1l, in a semi-circularnotch, in the support g, which may bea part of the rough tree rail, it,of the vessel, or other convenient part, andthe Vdavit is iinished bythe curved part f, with an eye 10, as usual, taking by a hook, orswivel, the hoisting tackle, one block ,.of which is shownin place.

It will now be seen, that the davit is supported, and can be used toraise any article, such as an anchor, or boat, up, and swinging itaround over the bulwarks, and allow it to be lowered onto the deck, orlowered overboard; and when not in use, the

forelock l1, is to be opened and the davit lowered down alongside thebulwarks and secured as seen in Fig. 2. The socket d, turning on itsjoint 5, allows of the lowering of the davit, still retaining the foot,and when required for use, all that is necessary is, to hoist the davitinto place, and secure it by the forelock 11, or similar means.

The holes 8,V and 9, may be bored in the parts c, and d, toallow theescape of water so as to prevent rusting.

This davit, although shown as applied to the inside of the vessel, maybe applied to the outside, by the use of a vertical instead o ahorizontal flange, or may be applied in any other convenient situation.

In the old mode of fitting davits, the lower end is simply set in anopen socket, so that when not in use, it usually stands in its place,and is in the way of the rigging; and Aalso is a heavy weight, which, inlashing about in a storm, strains or damages thebulwarks; and alwaysinterferes with the free motion ofthe ship; and when the davit7 ishoisted out and, laid down, if the anchor is wanted in a hurry, it isgenerally when secured, ready for use: For the purpose of raising, orlowering, a rope to the yard arm, and davit e, for the purposes, and asdel0 or other convenient place, may be employed. scribed and shown.

I do not claim any of the separate parts In witness whereof I havehereto set my themselves, but signature i this thirtieth day of December5 I do claim as new, and of my own invenone thousand eight hundred andfifty one.
